Cleaner for the Time Domain Reflectometer Tank Level Indicator
AI Overview
The Navy seeks an innovative cleaning solution for fouled Time Domain Reflectometer sensors that measure fuel levels on DDG 51 destroyers. The technology must restore sensor accuracy without requiring ships to cease operations or undergo costly tank maintenance, thereby improving mission readiness and fuel management reliability.
This summary is AI-generated from the official solicitation.
Key Details
Official Description
Fouling on the TDR sensor used for TLI is a persistent problem. The TDR is necessary to provide accurate and precise readings for fuel measurement. Over time, TDRs can experience sensor fouling through a buildup of crystallization and other contaminants on TDR rods and tubes, contributing to false readings or other failures if not properly maintained and cleaned.
The operational readiness of the U.S. Navy's DDG 51 Arleigh Burke-class destroyers is being undermined by a persistent and unsolved e...

Cleaner for the Time Domain Reflectometer Tank Level Indicator
- Q1 answered: The DDG TDR TLI is identified as the Vegaflex 67 and 82N models (previously unanswered).
- Q2 answered (sensor details):
- Configuration: rod (not cable), Vegaflex 67 and 82N.
- Length: varies by tank geometry; assembled from 1, 2, and 4 foot screw-together sections.
- Diameter: coated rods measure 16.43 mm.
- Material: Cu-Ni with grey powder-coated epoxy.
- Stilling tube: shroud/tube inside diameter is 37.55 mm; centering spacers (every 4 feet) are 35.64 mm in diameter, leaving roughly 1.9 mm of clearance per side.
Why it matters: Applicants can now confirm the exact sensor models and physical dimensions needed to scope compatibility, mounting, and fabrication for the TLI sensor, including the rod-in-tube clearance.

Cleaner for the Time Domain Reflectometer Tank Level Indicator
- New Q&A added (Q1): An applicant asked whether the DDG TDR TLI is the Vegaflex 82 series or another model/brand. No answer is shown yet, so the brand/model identity of the required sensor is still unconfirmed.
- New Q&A added (Q2): An applicant requested sensor specifications for the TLI: whether it uses a rod or cable configuration, rod/cable length, diameter, and material, and the gap between the rod and the inside surface of any stilling tube. No government answers are included in this version; the text only contains the questions.
Why it matters: Applicants building to a specific sensor design (rod vs. cable, dimensions, materials, stilling tube clearance) cannot price or engineer a compliant solution until the government responds. Watch for the answers to these questions, since a named brand or specific dimensions could narrow which products qualify and affect your technical approach and cost estimate.
